Definitions

  • the invention is fitted in the technical sector of tubular heat exchangers, concretely in the cleaning process of their tubes.
  • the present invention refers to a protection device for the cleaning in safe way of the tubes of tubular heat exchangers by means of high-pressure flexible pipe, which avoids the possibility of an uncontrolled exit of the cleaning pipe and nozzle toward the operation zone and allows to evacuate the projections of particles toward a confined place.
  • the protection device is designed so that its handling is easy in all and each one of its use operations, maintaining the safety during all cleaning process.
  • characteristics of design of the device stand out:
  • the figure 1 shows the front view and the figure 2 its respective plan view of the device in keeping with the invention assembled on the flange of a tubular heat exchanger in working position for the cleaning of one of its tubes.
  • the device includes some rollers (1) that turn freely on the pivot screws (2) assembled on the rotacional displacement tool (3). These rollers (1) provide the guidance of the cleaning hose (4) in its displacements and prevent its uncontrolled exit toward the operation zone as essential function of the device.
  • the screw coupling (5) is located, which is joined to the T-connector (6) by means of the reduction nut (7), which is rigidly joined to this connector (6).
  • This joint between the connector (6) and the tool (3) allows to turn freely to the connector (6), on its axis, regarding the tool (3).
  • the function of the T-connector (6) is that of being able to point toward a safe position, through its mouth located in perpendicular with the cleaning hose (4), the projections of particles toward the exterior of the tube by the part where the cleaning task is carried out. This mouth is incorporated to be able to connect to it a drainage or a sucking device, and in that way to make effective its function as safety measure.
  • the screw couplings (5, 8), the connector (6) and the nuts (7, 9) shape the screened and capture system of projected particles.
  • the displacement of the nut (9) has for object the coupling of this system with the front surface (10) of the exchanger to obtain its maximum effectiveness, endowing to this system of a regulation so that the coupling is possible on all kinds of heat exchangers, independently of which is the mooring contour elevation of the device regarding the front surface (10) of the exchanger, contour elevation that is determined by the design of the exchanger.
  • the two described sliding joints provide to the device of a mobility with double degree of freedom on the front surface (10) of the exchanger, which allows to position easily, by means of combination of both slides, the cleaning hose (4) in line with the tube to clean.
  • the jaw clamps (21) are the fixing elements of the guide pipe (16) to the flange (22) of the exchanger, achieving the complete immobilization of the pipe (16).
  • the jaw clamps (21) are moored to the flange (22) by gripping of this between the jaw clamps (21) and the mooring nuts (23).
  • the press screw (24) and press nut (25), both rigidly joined to each other, are joined to the jaw clamp (21) and turn freely with regard to this, said turn generates the longitudinal displacement of the mooring nut (23) which allows the gripping of the flange (22).
  • the jaw clamps (21) are moored to the guide pipe (16) by embrace of these to the pipe (16), this embrace is achieved operating on the press screws (26) which are assembled on the own jaw clamps (21).
